Today, the importance of information security to modern people is self-evident, and many users encrypt their personal information for the purpose of protecting information security. However, in the prior art, only the personal information is usually encrypted in the display page, and the personal information is not encrypted in the database, which easily causes that after the database is stolen, the personal information in the database is leaked, so that the security of the personal information of the user is greatly threatened, which brings trouble to the user. Accordingly, embodiments of the present invention provide a method and an apparatus for protecting personal information, so as to alleviate the above problems.
In order to facilitate understanding of the embodiment, a detailed description is first given of a personal information protection method disclosed in the embodiment of the present invention.
In one possible embodiment, the present invention provides a method for personal information protection. Fig. 1 is a flowchart of a method for protecting personal information according to an embodiment of the present invention, where the method includes the following steps:
step S102: and configuring corresponding encryption information for the personal information respectively transmitted by one or more user terminals.
The encryption information includes first encryption information and second encryption information which are related to each other, and the personal information is information of a user who uses a corresponding user terminal of the one or more user terminals.
Step S104: and carrying out irreversible encryption on the personal information by using the first encryption information to obtain a first ciphertext, and carrying out reversible encryption on the personal information by using the second encryption information to obtain a second ciphertext.
Step S106: and storing the first ciphertext, the second ciphertext and the first encryption information into an encryption database accessed through a preset program, and sending the first ciphertext to a service server.
The embodiment of the invention has the following beneficial effects: the embodiment of the invention provides a personal information protection method, which comprises the steps of firstly configuring corresponding encrypted information for personal information sent by one or more user terminals respectively, then carrying out irreversible encryption on the personal information by utilizing the first encrypted information to obtain a first ciphertext, carrying out reversible encryption on the personal information by utilizing second encrypted information to obtain a second ciphertext, finally storing the first ciphertext, the second ciphertext and the first encrypted information into an encrypted database accessed through a preset program, and sending the first ciphertext to a service server. The personal information protection method and the personal information protection device of the embodiment of the invention respectively obtain two ciphertexts by encrypting the personal information twice by utilizing the encryption information, and store the two ciphertexts and the encryption information into the encryption database accessed by the preset program, thereby greatly improving the security of the personal information of the user.
In practice, each user is distinguished by marking the encrypted information and the ciphertext information corresponding to the user information of a certain user with the user ID of the user.
Specifically, the first encrypted information, the second encrypted information, the first ciphertext and the second ciphertext corresponding to the personal information of the one or more user terminals are marked with corresponding user IDs.

The first encryption information is used for encrypting the hash value of the personal information instead of encrypting the personal information to obtain a first ciphertext, and the first ciphertext forms double encryption on the personal information, so that the personal information security of the user is further improved.
Step S206: and storing the first ciphertext, the second ciphertext and the first encryption information into an encryption database accessed through a preset program, and sending the first ciphertext to a service server.
It should be further noted that the encrypted database can be accessed only through a program preset by a user, so that the first ciphertext, the second ciphertext and the first encrypted information stored in the encryption server cannot be leaked.

Step S212: and determining second encryption information according to the first encryption information, decrypting the corresponding second ciphertext based on the second encryption information to obtain personal information corresponding to any user terminal, and returning the personal information to any user terminal.
After obtaining the personal information corresponding to any user terminal, if necessary, the personal information can be returned to the service server for processing (for example, a part of the personal information is masked with an asterisk), and then returned to the user terminal.
In summary, in the method and apparatus for protecting personal information according to the present invention, first, corresponding encryption information is configured for personal information sent by one or more user terminals, then, the first encryption information is used to perform irreversible encryption on the personal information to obtain a first ciphertext, the second encryption information is used to perform reversible encryption on the personal information to obtain a second ciphertext, and finally, the first ciphertext, the second ciphertext, and the first encryption information are stored in an encryption database accessed by a preset program, and the first ciphertext is sent to a service server.
